So I finally got around to playin it last night for a bit, holy crap I was bad at it. Got killed by the first guy like 5 times.
I was playing on Normal and without having done the tutorial yet, since I only had a few minutes to try it out, so I'm gonna give it a proper go later today. Even with just that though, it looked really really cool! Much more interested than I was previously.
I loved the fact that he somehow slid UP the stairs on his knees, that was funny.
EDIT:
Okay, now I've played it properly, I really am liking this a lot.
At first I was kind of underwhelmed, and didn't really like it all that much. Mostly getting frustrated with how easy it was to burn through the Boost/Attack meter.
When the boss arrived though, I really got into it, and I found myself having a lot of fun. The boosting looks incredibly cool and I love boosting around the stage going in and out of bullet time to attack enemies. I find that I hardly use cover unless i'm in trouble or cooling the suit down.
Aki-at even told me about how you can throw a grenade, then bullet time and shoot the grenade in mid-air! That was brilliant!
On my second playthrough I found the Sniper's Rifle, then discovered you can kill the Mech Operators and commandeer the mechs! Awesome!
One question though, what does smoking do? I've done it a few times but not sure what it actually is used for.
